Does any one know what medicenes were put in small glass vials besides the obvious morphine?

I live in Saipan at the very top of “Death Valley” as featured in the movie “Wind Talkers” and we are always finding things left from the great battle including neat little (very small) bottles and glass vials. We know about the morphine one shots and have several but now finding vials of powder, one I am almost sure is sulphur because of the color, any clues?
